RARE Gray Star Sapphire Gem!

Here we have a light gray natural star sapphire with a strong 6-ray star! 9x8mm, 6mm tall, 5.5 carats. BEAUTIFUL opaque, included, earth-mined gem with glittering white shimmers! This gem would make a beautiful ring (engagement or otherwise); at 9 on the Mohs scale, sapphires are second to diamonds in hardness and are great for daily wear. Please see video for the phenomenon of asterism, where rutile silk within the gem aligns to show a star that floats along the surface when illuminated by a direct light source such as the sun or a bright indoor light. I’m a collector, not a gemologist—while I’m almost positive it hasn’t been chemically treated (heated or diffused) because there’s red sediment on the gem that probably would’ve washed off in a chemical bath, I can’t confirm via testing. I doubt it was here’s because of the asterism. I also believe it’s a Ceylon sapphire, meaning it likely originated in Sri Lanka.
